My foreskin is fairly tight ( i am aware of this condition) and I have been doing stretching exercises and they seem to be slowly working, I can retract my foreskin just over my penis with very little discomfort, just if i pull it further back part of my penis becomes thinner than the rest.

But to the point, when i pull it back this far, my glans begins to point down a little bit and to the left, not drastically to the left but probably an abnormal amount, I look round at the back and it seems like the frenulum is being pulled a little bit to the left side. It looks a bit like it attached a bit more on one side. I think I felt a mild discomfort while having sex but there was no blood.
Help please?
